The plan is finished. The medal is in a drawer. And there is an odd flatness to the following week, which is partly physiological and partly the absence of the thing that gave every Tuesday a point.
Before deciding anything, take two or three weeks of easy running with no structure. Decisions made in the week after a race are made by someone who is still tired.
Option 1: the marathon
The obvious next step, and a genuine one. Be clear-eyed about what changes: the long run stops being a session and becomes a logistical event, weekly volume roughly doubles for many people, and the failure modes are different. A bad half is uncomfortable. A bad marathon is a long walk.
Good choice if: you enjoyed the long runs more than the fast ones, and you have the hours.
Option 2: get faster at the half
Underrated. Running the same distance meaningfully faster requires better threshold work, better pacing and usually better strength — and it delivers a much clearer signal about whether you are improving than adding distance does.
Good choice if: your first half was about finishing and you want to know what you can actually do.
Option 3: shorter and sharper
Drop to 10K or 5K for a block. It is humbling — the paces are uncomfortable in a completely different way — and it tends to make the half feel easier when you come back to it. It also takes far less time per week.
Good choice if: your life has less time in it than it did during half training.
Option 4: change the test entirely
A hybrid fitness race asks a different question: can you still run when your legs and lungs have been asked to do something else first? Most half-marathoners discover two things quickly — their aerobic base transfers well, and their upper body and their ability to move a load do not.
It is a useful reality check, and for a lot of runners it is the thing that finally makes strength training feel worth doing.
How to choose
Ask what you enjoyed. Not what you achieved — what you actually enjoyed doing on a Tuesday. Endurance training is a long game and the athletes who keep improving are the ones who chose a direction they wanted to spend six months in.
